Linux / *BSD resources

There are many web sites and newsgroups containing resources
about Linux,
FreeBSD,
OpenBSD, NetBSD and free / open source software in
general: here are some sites divided in categories.

Resources about specific Linux
distributions

The first resources available are the ones you can find on the
site of the distribution you installed or you want to install.
The most important distributions
are: Red Hat,
Suse, Debian, Mandriva, Ubuntu
and Slackware
but there are a lot of more distributions, each one with its own site
so you may have a look at DistroWatch,
a site containing a lot of updated information about the various
distributions.

If you want to find resources about the various components of
Linux distributions you can go to sites dedicated to the kernel and to the
graphic server X.Org
or XFree86.

A free-to-download guide to the basics of command line use and shell scripting, on many common programs used on the command line, as well as more advanced topics is The Linux Command Line.
